Untargeted global metabolomic profiling of healthy dogs grouped on the basis of grain inclusivity of their diet and of dogs with subclinical cardiac abnormalities that underwent a diet change.

Objective: To compare metabolomic profiles of dogs eating grain-free (GF) versus grain-inclusive (GI) diets (1) for healthy dogs at baseline and (2) for dogs with subclinical cardiac abnormalities at 12 months after a diet change.

Sample: Serum samples from 23 dogs eating GF diets and 79 dogs eating GI diets, of which 17 (8 eating a GF diet and 9 eating a GI diet) were reevaluated 12 months after a diet change.

Procedures: Metabolomic profiles were developed by means of ultrahigh-performance liquid chromatography-tandem mass spectroscopy of serum samples.

Effect of diet change in healthy dogs with subclinical cardiac biomarker or echocardiographic abnormalities.

Background: A recent study showed higher high-sensitivity cardiac troponin I (hs-cTnI) concentrations in healthy dogs eating grain-free (GF) compared to those eating grain-inclusive (GI) diets.

Hypothesis/objectives: Healthy dogs with subclinical cardiac abnormalities eating GF diets at baseline will show improvements in cardiac biomarkers and echocardiographic variables after diet change, whereas healthy dogs eating GI diets at baseline will not improve.

Animals: Twenty healthy dogs with subclinical cardiac abnormalities (12 Golden Retrievers, 5 Doberman Pinschers, 3 Miniature Schnauzers).

Fluctuations in body satisfaction across situations.

Although the variable nature of body image was underscored by Schilder (The image and appearance of the human body. New York: International Universities Press, 1950), few investigators have addressed the stability of body image or its sensitivity to variation in environmental or situational conditions. Most researchers have assumed that body image is a stable characteristic.
